DETAILED DESCRIPTION

Techniques described herein disclose a solution for calibrating print heads of a wall painting printer with multiple print heads. Embodiments of the present application provide a wall painting machine, a print head calibration method, a device, and a control terminal. The drawings illustrate preferred embodiments of the application. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the application, and are not intended to limit the application. In order to improve the printing efficiency, a wall painting machine includes multiple print heads that are sequentially distributed in a specified direction and can be printed simultaneously.

For a wall painting machine with multiple print heads, in order to ensure that the print positions of two adjacent print heads are connected, that is, there is no overlap or gap, before the wall painting machine leaves the factory, the print position is calibrated. At present, it can be adjusted by the processing accuracy of parts and components and mechanical assembly tests. However, this process is very tedious, complicated, and not reliable enough, because there may be certain errors in each batch of processed parts, and the experience of each operator has a greater impact on the calibration results. In addition, when the ambient temperature changes, the print position of the print head that has been calibrated may change, and recalibration is very difficult for the user.

In view of the above problems, an embodiment of the present application provides a wall painting machine, as shown in FIG. 2, including: a plurality of print heads, among them each print head includes a plurality of nozzles. Among the multiple nozzles of each two print heads adjacent to the print position, there are nozzles with overlapping print positions. The nozzles of the print head can be set to open or close.

Using a wall painting machine with multiple print heads for wall painting printing can improve printing efficiency. In addition, among the multiple nozzles of each of the two print heads adjacent to the print position, there are nozzles with overlapping print positions, and the nozzles of the print head can be set to be turned on or off. The closed setting realizes the calibration of the print position of the print head. For example, the print positions of two adjacent print heads are connected, that is, there is no overlap or gap.

In addition, when the environment changes, the print position of the print head changes accordingly. The opening or closing of the nozzles of the print head can be reset to facilitate recalibration. In one embodiment, the distribution direction of the multiple print heads can be flexibly set based on the printing direction and various other requirements in practical applications.

For example, as shown in FIG. 2, multiple print heads can be sequentially distributed in the horizontal direction, and multiple print heads can be printed in the vertical direction. That is, during the printing process, the wall painter moves one position in the horizontal direction. , The print head prints in the vertical direction, from top to bottom, or from bottom to top;

For another example, multiple print heads may be sequentially distributed in the vertical direction, and multiple print heads may print in the horizontal direction. For the wall painting machine, correspondingly, an embodiment of the present application further provides a method for calibrating a print head of a wall painting machine. As shown in FIG. 3, the method may include the following steps:

Step 21: The calibration interface of the wall painting machine is displayed, and the calibration interface includes a setting option for setting whether to enable or disable the nozzle of each print head.

Step 22. Based on the setting operation on the setting options, record the nozzles opened by each print head.

Step 23. Control the wall painting machine to print on the wall using the nozzles opened by each print head. The color blocks printed by each print head on the wall are used to set the nozzles on or off for the next time. Reference.

By adopting the print head calibration method of the wall painting machine shown in FIG. 3 described above, the print head's nozzle can be set on or off to achieve the calibration of the print position of the print head. The print positions of the print heads are connected, that is, there is no overlap or gap. The solutions provided in the present application will be described in detail below with reference to the drawings and specific embodiments.

FIG. 4 is a detailed flowchart of an embodiment of a method for calibrating a print head of a wall painting machine according to an embodiment of the present application. As shown in FIG. 2, a wall painting machine includes 4 print heads, and the head is distributed horizontally, and the printing direction is vertical. As an example, the method flow is described, which can include the following steps:

Step 31: The calibration interface of the wall color drawing machine is displayed. The calibration interface includes a setting option for setting the nozzles of each print head to be turned on or off.

In the embodiment of the present application, the wall painting machine includes multiple print heads, each print head includes multiple nozzles, and the number of nozzles included in different print heads may be the same or different, which is convenient for manufacturing, installation, and use. The number of nozzles included in each print head may be the same.

In one embodiment, as shown in FIG. 2 and FIG. 5, the wall painting machine includes 4 print heads, which are distributed horizontally, and are print head A, print head B, print head C, and print head D from left to right, respectively. That is, print head A and print head B are adjacent, print head B and print head C are adjacent, print head C and print head D are adjacent.

Each print head includes 180 nozzles, and among the multiple nozzles of every two adjacent print heads, there are nozzles with overlapping print positions, and the number of nozzles with overlapping print positions can be flexibly set according to actual needs. For example, For the convenience of description, the 180 nozzles of each print head are in the order of 1-180 from left to right. The number of nozzles with overlapping print positions between print head A and print head B can be 10, that is, The print positions of the 171-180 nozzles of print head A overlap with the print positions of the 1-10 nozzles of print head B. It can be understood that the print positions overlap in the vertical direction.

Similarly, the number of nozzles with overlapping print positions between print head B and print head C can be 10, that is, the print positions of the 171-180 nozzles of print head B and the print positions of 1-10 nozzles of print head C overlap The number of nozzles with overlapping print positions between print head C and print head D may be ten, that is, the print positions of the 171-180 nozzles of print head C and the print positions of 1-10 nozzles of print head D overlap.

In the calibration interface, for each print head, there is a setting option for setting the nozzles on or off. For example, as shown in FIG. 5, through the setting options, you can set the first to several nozzles of each print head to open. , The remaining nozzles are closed.

In practical applications, the nozzles that are opened and closed by default can be flexibly set based on actual needs. For example, all nozzles can be opened by default, or the 1-170th nozzle of printhead A can be opened by default, and the 1-170th nozzle of printhead B can be opened by default. Nozzle is turned on, the 1-170th nozzle of printhead C is turned on, and the 1-180th nozzle of printhead D is turned on, that is, for printhead A, printhead B, and printhead C, each of which is adjacent to the right side of the printhead Nozzles with overlapping print positions are closed.

After displaying the calibration interface, the user can set the opening and closing of the nozzles of the print head through the setting options in the calibration interface.

The calibration interface may also include an inspection test option for indicating the start of printing, as shown in the “inspection test” option shown in FIG. 5, and the user can start the print test by operating the inspection test option.

The calibration interface can also include a confirmation option indicating that the calibration is complete, as shown in the “Save parameters” option shown in FIG. 4. After the calibration is completed, the user can save the parameters for subsequent formal walls by operating the confirmation option. Step 32: Based on the setting operation of the setting options, record the nozzles opened by each print head.

In the embodiment of the present application, when a user performs a setting operation for opening and closing a print head based on a setting option, a default setting may be used in a first inspection test, and a non-first inspection test may be based on actual needs and based on a previous During the test, the color blocks printed by each print head are detected, and the nozzles of the print head are opened or closed.

For example, in the color block printed by each print head during the previous inspection test, when there is a gap between the color blocks printed by two adjacent print heads, the corresponding one closed before one of the print heads can be turned on. Nozzles, when there is overlap between the color blocks printed by the corresponding two print heads, the corresponding nozzles opened before one of the print heads can be closed.

Based on the setting operation, in this step, the nozzles opened by each print head are recorded and used for subsequent wall painting printing when the verification test is started. Step 33: The wall painting machine is controlled to print on the wall by using the nozzle opened by each print head.

When the calibration interface includes a calibration test option, after the calibration test option is triggered, the wall painter can be controlled to print on the wall by using the nozzle opened by each print head. In one embodiment, in order to facilitate distinguishing the color blocks printed by each print head, a corresponding color can be set in advance for each print head, and each two adjacent print heads have different corresponding colors, and accordingly, when printing, control the wall painting machine to print on the wall using the nozzles opened by each print head according to the respective colors of each print head. The schematic diagram of the printed color blocks can be shown in FIG. 6, The color blocks A-D are the color blocks printed by the print head A-print head D, respectively.

It can be seen from FIG. 6 that the print positions of some print heads overlap, and there are gaps in the print positions of some print heads. The printed color block can be used as a reference for the next setting of the nozzle opening or closing of the print head. That is, return to step 31 above to start the next verification test, that is, continue to calibrate the print position of the print head of the wall painting machine.

Step 34: When the confirmation option in the calibration interface is triggered, parameters indicating nozzles that have been turned on for each print head are saved. In the embodiment of the present application, the print position of the print head can be calibrated by repeating the above steps 31 to 34. After the calibration is completed, for example, the printed color blocks are shown in FIG. 7, and every two adjacent prints the print positions of the heads are all connected, that is, there is no gap or overlap. At this time, the user can operate the confirmation option in the calibration interface. For example, the “Save parameter” option in FIG. 5 is triggered when this option is triggered. After that, the parameters representing the nozzles that have been turned on for each printhead are saved for subsequent formal wall painting printing.

Further, in practical applications, other printing parameters required for wall color printing can be set based on parameters indicating the nozzles that each print head has turned on, for example, the number of columns or rows printed each time, feathered The number of nozzles, and the step length of each print, etc., and how to set it can be flexibly set according to the actual characteristics of the wall painter and the printing needs.
